Demonic · Goetic Spirit · c. 1577 CE
Furcas
Also called Forcas, Forras (per Wikidata)
The only spirit in the seventy-two ranked as a Knight. He appears as a cruel old man with a long beard and hoary hair, armed on a pale horse, and teaches philosophy, astrology, rhetoric and logic alongside palmistry and divination by fire.

Single lineage
Form. A cruel old man with a long beard and hoary hair, riding a pale horse with a sharp weapon.
Offices. Teaches philosophy, astrology, rhetoric, logic, chiromancy and pyromancy perfectly.
Note. The only spirit in the seventy-two given the rank of Knight.
Identity
Where does the name come from?
Where it was actually worshipped
None. The Ars Goetia is a conjuring manual and not a liturgy: its spirits are constrained, put to work and dismissed, never housed or offered to. Not one of the seventy-two has a temple, a shrine, a festival or a place-name anywhere.
A figure with temples and a figure that only ever existed on a page are different kinds of thing, and the difference is easy to lose once both are entries in a list.

- Position in list: 39, 50 depending on the text

Weyer lists this spirit 39th of his sixty-nine, with substantially the same offices. His order is not the Goetia's — the two texts arrange the same spirits quite differently.

Teaches philosophy, astrology, rhetoric, logic, chiromancy and pyromancy perfectly.
“The Fiftieth Spirit is Furcas. He is a Knight, and appeareth in the Form of a Cruel Old Man with a long Beard and a hoary Head, riding upon a pale-coloured Horse, with a Sharp Weapon in his hand.”
Connections
What is it connected to?
Nothing, and that is what the source says. The Ars Goetia gives Furcas a rank, a number of legions, a list of offices and a seal, and no relationship to any other spirit in the book — no lineage, no faction, no quarrel. Sixty-seven of the seventy-two are in the same position. A catalogue of self-contained entries is what that text is, and the emptiness here is the shape of it rather than work outstanding.

Chosen by proximity rather than by popularity: the same pantheon first, then the same rank, then the same kind of figure.

Asmoday
King · Goetic Spirit
Commands seventy-two legions, one for every spirit in the book. He is the Asmodeus of Tobit, who killed Sarah's seven husbands and was driven into Upper Egypt by Raphael, and behind that the Avestan Aeshma-daeva, the demon of wrath — one of very few Goetic spirits with an ancestry that can be traced.

Astaroth
Duke · Goetic Spirit
The Canaanite goddess Astarte, three thousand years on, made a male duke of hell with her name intact. The Goetia has him discourse willingly on the fall of the spirits, and warns the operator to hold a ring to his face against the stench of his breath.

Beelzebub
Prince · Infernal Court
'Lord of the Flies' — a Philistine god of Ekron whose name was almost certainly deformed as a Hebrew insult, then inherited by Christian demonology as the second power of hell.

Belial
King · Goetic Spirit
In the Hebrew Bible beliya'al is not a name but a word meaning worthlessness; by 2 Corinthians it is a person, and by the Goetia a king in a chariot of fire handing out senatorships. The text says he was created next after Lucifer and fell among the first, and will not answer truly without gifts.
The Spirits of Affliction
Group of Named Spirits · Deliverance tradition
The remaining 'spirit of X' phrases, grouped because the tradition's whole method stands or falls on how they are read.

Bael
King · Goetic Spirit
First of the seventy-two and, by the Goetia's own account, chief among them — a three-headed thing on spider's legs, ruling in the east and granting invisibility. The name is the Canaanite storm god Baal, three thousand years and one demotion later.
